Immunogen conjugates comprising amino-functionalized haptens coupled through a carbonyl bridge to amino groups in immunogenic proteins and polypeptides. The resulting simple urea linkage in the conjugate is hydrophilic and contributes essentially no haptenic determinants. The immunogen is characterized by a high epitopic density. The method involves reaction of the hapten with a carbonyl diimidazole followed by addition of the protein or polypeptide carrier. Protein crosslinking problems common to prior art coupling methods are avoided.
免疫原轭合物包括通过羰基桥与免疫原蛋白和多肽中的氨基偶联的氨基官能化触酶。共轭物中的简单脲基连接具有亲水性,基本上不产生合酶决定簇。免疫原的特点是表位密度高。该方法涉及合酶与羰基二咪唑反应,然后加入蛋白质或多肽载体。避免了现有技术偶联方法中常见的蛋白质交联问题。
